Interrelations between heart rate, hypertension, and the other cardiovascular risk factors in Krasnoyarsk Krai population

Aim. To evaluate the heart rate in the state of rest and to find its interrelations with gender, age, blood pressure level, estimated glomerular filtration rate, and metabolic syndrome components in the representative sample of Krasnoyarsk Krai population. Material and Methods. Within the framework of ESSE-RF study, the representative sample consisted of 1 411 Krasnoyarsk Krai inhabitants aged 25–64 with no history of beta-blocker intake. With IBM SPSS v. 22, we calculated the descriptive statistics and checked group disparities for statistical significance (significant at p≤0.05). Results. The median heart rate in the sample was 72 (66; 78) beats per minute. We found no significant disparities neither in gender (p = 0.182) nor in age groups (p = 0.084). The heart rate in hypertensive people (73 (68; 80) beats per minute) was significantly higher (p < 0.001) compared to those with normal blood pressure (71 (65; 76) beats per minute). Besides, the heart rate over 80 beats per minute was more prevalent in hypertension and prehypertension compared to normal blood pressure. Renal dysfunction was associated with a slight heart rate decrement, while hyperglycemia (blood glucose over 7 mmol/L), hyperuricemia, and obesity (both general and abdominal) were associated with increased heart rate. Dyslipidemia had no association with heart rate. Conclusion. In Krasnoyarsk Krai population, the heart rate significantly increased in people with hypertension, prehypertension, or at least one component of metabolic syndrome (hyperglycemia, obesity, or hyperuricemia). In patients with prehypertension and hypertension, the heart rate over 80 beats per minute was significantly more prevalent compared to people with normal blood pressure.
